I have timer, simple label with seconds. That label is automatically changing with Timer, it is simple and ok.
I have arc/circle implemented with radius strictly connected with seconds. My goal is to actualize this graphic, doing something like an analog clock.
Seoconds label are dynamically changing, but I cannot make arc changing. Is it normally possible? How to make that circle to increment arc (to actualize graphic in viewcontroller?)
Thank You!
// ViewController.swift
import UIKit
class ViewController: UIViewController {
let circle = Circle()
let button = Button()
let timeKeeper = TimeKeeper()
override func viewDidLoad() {
super.viewDidLoad()
timeKeeper.runTime()
//label clock setup
TimeLabel.sharedTime.font = UIFont.systemFont(ofSize: 13)
view.addSubview(TimeLabel.sharedTime)
TimeLabel.sharedTime.translatesAutoresizingMaskIntoConstraints = false
//circle clock setup
view.addSubview(circle)
circle.translatesAutoresizingMaskIntoConstraints = false
}
}
// TimeKeeper.swift
import UIKit
struct TimeLabel {
static var sharedTime = UILabel()
static var sharedCountTime = Timer()
static var sharedTotalSeconds = 0
}
class TimeKeeper {
func runTime() {
TimeLabel.sharedCountTime = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(increaseTime), userInfo: nil, repeats: true)
}
@objc func increaseTime() {
TimeLabel.sharedTotalSeconds += 1
TimeLabel.sharedTime.text = String(TimeLabel.sharedTotalSeconds)
}
}
// Circle.swift
import UIKit
class Circle: UIView {
override init(frame: CGRect) {
super.init(frame: frame)
self.backgroundColor = UIColor.clear
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func setCircle() {
let center = CGPoint(x: frame.size.width/2, y: frame.size.height/2)
let circle = UIBezierPath(arcCenter: center, radius: frame.size.width * 0.4, startAngle: 0, endAngle: .pi / 60 * CGFloat(TimeLabel.sharedTotalSeconds), clockwise: true)
circle.stroke()
}
override func draw(_ rect: CGRect) {
setCircle()
}
}
Please format code for readability.

}May be I missed something, but I do not see the equivalent of runTime() for circle, to call for drawing.
Why not calling a redraw for circle at line 33. Of course setCircle should use sharedTotalSeconds
